Is there aa way to use ipsec for a site-to-site vpn in preference to the ssl implementation. I would love to use the ssl stuff but I have a significant investment in Linsys RV042 routers at a number of home offices.

I would like to connect these home offices to my Zeroshell box at the main office so that the voip extensions can connect to the PBX but i cannot do this with the ssl implementation afaik.

to my knowledge the "host to lan" implementation does not work with PSKs. although i do not currently have a box up to confirm this on. if it does that I suppose I could just use that section to build a lan-to-lan vpn
